Send link to this page print Your Nexans contact on this page
PVC/Nylon Insulated Cable, Copper Conductors, 600 Volts, 90ºC Dry Rated - LEAD FREE
Standards
National  UL 719; UL 83
Description

Application

Nexans non-metallic sheathed ENERGEX® NM-B cable is used in normally dry installations in residential wiring, as branch circuits for outlets, lighting and other residential loads.  Its applications are outlined in NEC 2008 and NEC 2011 Article 334. NM-B is rated at 600 volts and although it is rated at a conductor temperature of 90ºC dry , its ampacity is limited to 60ºC according to the NEC 2008 and NEC 2011.  It may be fished through masonry or tile walls, where not exposed or subject to excessive moisture or dampness.

Nexans NM-B cables are LEAD FREE and RoHS compliant.

  

Construction

Conductor
Solid 14 to 10 AWG annealed soft bare copper per ASTM B3. 
Stranded 8 AWG and larger annealed soft bare copper per ASTM B3 and B8.

Insulation:
Color coded polyvinyl chloride (PVC) compound with a nylon covering meeting the required thickness of Type THHN.  Conductor insulation is rated 90ºC.

Ground:

Notes:

• Where stated, “nominal” and “approximate” values are provided for information purposes only and are subject 
to standard manufacturing tolerances.
• Ampacities are in accordance with NEC 2008 and NEC 2011 Article 310.15 and 334.80, which are based on NEC 2008
Table 310.16 or NEC 2011 Table 310.15(B)(16) for conductors in a raceway or direct buried at 30°C ambient temperature
and 60°C rated conductors.
• For correction factors for different ambient temperatures and ampacities at different conductor temperature ratings see 
NEC 2008 Table 310.16 or NEC 2011 Table 310.15(B)(16).
• NEC 2008 and NEC 2011 Article 240.4(D) requires that overcurrent protection not exceed 15 amperes for 14 AWG, 
20 amperes for 12 AWG, and 30 amperes for 10 AWG copper conductors after any correction factors for ambient 
temperature and number of conductors have been applied. Exceptions to this may be covered in NEC 2008 and 
NEC 2011 Article 240.4(E) through (G).

¹  Insulation color code for 2 / 2 conductor cable is Black, White, Red, and White with Red stripe.  Cable ampacity 
is based on the White and White with Red Stripe conductors being connected as the neutrals for the system.
². Insulation color code for 4 conductor cable is Black, White, Red and Blue.  Cable ampacity is based on the 
4th conductor being connected as the neutral conductor of a balanced 3 phase system.
